>Centrifuge rotor is the main accessories. In short, the host can be divided into centrifuge rotor and removable (turn) two parts, a multi-functional host can be assigned a number rotors usually rely on different models of the rotor to meet the different needs to achieve its "multi-functional "This will effectively reduce procurement costs, but to buy time to pay attention to the choice easy disassembly of the centrifuge rotor, a general centrifuge rotor spindle and directly with manufacturers in order to reduce noise and often the host of the rotor with degrees Has done quite high, but the biggest drawbacks is easy with the main rotor killed inconvenience caused by the demolition, and this with the rotor motor with the way there are still a very strong direction, the direction of the rotor and spindle motor with shift occurred Will have a greater impact on the noise of the whole life, serious faults will cause the main axis, the rotor blast. Germany as sigma centrifuge is used to expand the way jacket in the main rotor fixed, no matter how long this can be easy disassembly of the rotor, will not be killed. The most commonly used, including fixed-angle rotor and the rotor rotor level. Rotor Qi, of course, the more the more full-function, so I chose the rotor normally based on the capacity of the samples and used centrifuge to choose the conditions, usually turn their back on the level and the angle of a turn, high-capacity (low speed) of the rotor and small-capacity high-speed rotor Each one based on the work of the different needs of rotor other choice.

Angle in the centrifuge rotor tube to maintain a fixed angle centrifuge, you can use a high speed, centrifugal precipitation after the tube at the end of the slope. The rotor has a greater capacity, can usually be assigned a different "adapters" to "fixed" the capacity of the small sample tubes, for example, 6 x 85ml of the rotor can be placed in each hole 85ml centrifuge tubes, can take 15-20ml or 50ml centrifuge tubes To achieve a multi-use; However, due to the weight of the burden, high-capacity maximum speed of the rotor relatively small number of lower and therefore have to consider whether or not the maximum centrifugal force to meet the requirements of the experiment. Because the maximum speed of the other way round usually refers to the adaptation 2ml centrifuge rotor tube, and sometimes a little on the price of the rotor can buy a small number of centrifuges, can reduce the loss of expensive equipment. Some small high-speed desktop centrifuge also provide large and small fixed-angle rotor (with the respective 2ml/1.5ml and 0.5ml centrifuge tubes means, in fact, except the regular use of fixed-0.5ml centrifuge tubes and centrifuge each sample volume comparison , Select a general 2ml/1.5ml rotor, with adapter (for there is 0.2ml, 0.4ml, 0.5ml tube adapter) to meet the need. PCR be used if the tube but also equipped with an 8-pipe joint Rotor more convenient.

Angle of the rotor equipped with lid helps to reduce friction and reduce noise and prevent accidents, the use of rotor angle must be covered to build, if built centrifuge cavity will have a great swirl of heat resistance and friction, which is equivalent to the centrifuge motor and Refrigerator with the additional burden of the impact of the life of centrifuges. In addition there is a tightness of the rotor can be centrifugal air tightness, to prevent accidental release, the experiment in improving the environment is very important.

The level of the rotor with 2 or 4 basket, when they still hung in the vertical rotor, the basket have different adapter in order to meet the needs of different capacity of the centrifuge tube. When the rotor speed 600rpm more than the level reached after the centrifuge tube location, direction of the sample settlement along the centrifuge tube axial movement of the final settlement by the end of the tube, easy to collect. Because the fixed-angle rotor as a solid, hanging baskets, the highest level of speed compared to fixed angle rotor is much lower, limited to low-speed centrifuge. Basket of different adapter, you can put all types of centrifuge tubes, flat or even to meet the needs of the centrifuge - for example, the eppendorf centrifuge can be equipped with high-capacity multi-purpose adapter, making a number plate or microplate, deep Well plates, PCR plates, glass box, large-scale purification of nucleic acid purification kit board, and even cell culture bottle and can be centrifugal high-capacity centrifuge bottle with a common level of the rotor, at the same time help to save funds to meet the diverse needs of . So choose the more fit a wide range of the rotor, the better.

  The level of centrifuge rotors can settle in the tube wall rather than at the end of the inclined plane, but the level of the rotor speed is often worse than the models with fixed rotor is slower - sometimes unable to meet the needs of high-speed centrifuge, the requirements for high-speed, but also requested the deposition in the tube At the end of the micro-sample will be able to choose drum-type rotor, centrifugal means the level of control in fixed This is not aesthetically pleasing appearance, "a round biscuit box" inside the stent, can be relatively high speed centrifugation (14000rmp) and to ensure that gathered precipitation At the end of the tube.

More and more new type of rotor to the needs of the new born. The rotor material from light weight, high strength, low-cost aluminum alloy continuous innovation, there have been carbon-fiber rotor, rotor plastic rotor ultra-light, and so on, there will be pressure into a hollow aluminum alloy die angle so as to effectively reduce weight, so as to reduce the The electrical load and increase the capacity of the samples. The rotor and the adapter, can cover most of the direct high-temperature sterilization, temperature Kang Fu is also greatly enhanced to meet special needs. But in the high-speed rotors running, in-house will have a centrifugal stress, and therefore the use of a certain limit, in the light of the need and use the correct specification. More than a certain centrifugal stress when the limits will cause damage to the other way round too early, or even an accident, should strictly follow the manufacturer's description.
